Struct Edit 

pub struct Edit {
    pub start_byte: usize,
    pub old_end_byte: usize,
    pub new_end_byte: usize,
    pub start_position: Position,
    pub old_end_position: Position,
    pub new_end_position: Position,
}

Represents an edit to the source text

Fields

start_byte: usize

Start byte offset of the edit

old_end_byte: usize

End byte offset of the text being replaced (in old source)

new_end_byte: usize

End byte offset after the edit (in new source)

start_position: Position

Start position (line/column)

old_end_position: Position

Old end position before edit

new_end_position: Position

New end position after edit

Implementations

impl Edit

pub fn new( start_byte: usize, old_end_byte: usize, new_end_byte: usize, start_position: Position, old_end_position: Position, new_end_position: Position, ) -> Edit

Create a new edit

pub fn byte_shift(&self) -> isize

Calculate the byte shift caused by this edit

pub fn line_shift(&self) -> i32

Calculate the line shift caused by this edit

pub fn affects_byte(&self, byte: usize) -> bool

Check if a byte position is affected by this edit

pub fn overlaps_range(&self, range: &Range) -> bool

Check if a range overlaps with this edit

pub fn apply_to_position(&self, pos: Position) -> Option<Position>

Apply this edit to a position

pub fn apply_to_range(&self, range: &Range) -> Option<Range>

Apply this edit to a range

Trait Implementations

impl Clone for Edit

fn clone(&self) -> Edit

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Edit

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for Edit

fn eq(&self, other: &Edit) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
